Cancer induces immune suppression to overcome its recognition and eradication by the immune system. Cytokines are messengers able to modulate immune response or suppression. There is great interest in the evaluation of their changes during treatment in order to identify their relationship with clinical outcome. We evaluated 18 cytokines in breast cancer patients treated with eribulin before starting treatment (T0) and after four courses of therapy (T1). Longitudinal modifications were considered and cytokine clusters through PCA and HCPC correlated to patients’ outcomes were identified. Forty-one metastatic breast cancer patients and fifteen healthy volunteers were included. After clustering, we identified at T0 six patient clusters with different risk of relapse and death. At T1, only four clusters were identified, and three of them accounted for thirty-eight of forty-one patients, suggesting a possible role of treatment in reducing heterogeneity. The cluster with the best survival at T1 was characterized by low levels of IL-4, IL-6, IL-8, IL-10, CCL-2, CCL-4, and TGF-β. The cluster showing the worst survival encompassed high levels of IL-4, IL-6, IL-8, IL-10, CCL-2, and IFN-γ. A subgroup of patients with short progression-free survival (PFS) and long overall survival (OS) was comprised of in the cluster characterized by low levels of CCL-2, IL-6, IL-8, IL-10, and IL-12 at T0. Our data support the prognostic significance of longitudinal serum cytokine analysis. This approach may help identify patients for whom early treatment stop avoids needless toxicity or might justify treatment beyond early progression. Further investigations are required to validate this hypothesis.

Clinical Benefits

Trastuzumab deruxtecan (T-DXd, DS-8201), an anti-HER2 antibody–drug conjugate, has shown significant clinical benefits in HER2+ metastatic breast cancer patients. In the phase 2 DESTINY-Breast01 trial, T-DXd demonstrated an objective response of 60.9% and median progression-free survival of 16.4 months, laying the foundation for accelerated approval in HER2+ metastatic breast cancer patients who have received two or more prior anti-HER2-based regimens in the metastatic setting. Moreover, T-DXd exhibited promising antitumor efficacy against HER2-low-expressing metastatic breast cancer. Its distinctive side effect was pneumonitis, with a 13.6% incidence. It is approved in the US with boxed warnings for interstitial lung disease and embryo–fetal toxicity. This review focuses on preclinical, pharmacokinetic and pharmacodynamic data on T-DXd and clinical evidence of its antitumor activity (both as monotherapy and in combination) and tolerability in metastatic breast cancer.

1070 Background: Aromatase inhibitors represent a novel hormonal therapy for breast cancer. Aromatase is expressed in the ovaries, brain, bone and, adipose and breast tissue. Elevated WHR, representing a higher abdominal fat distribution, has been associated with both the development of and mortality from breast cancer. Therefore, we aimed to identify whether abdominal fat distribution could affect the outcome in metastatic breast cancer patients treated with AIs. Methods: A total of 46 metastatic breast cancer patients treated with first line hormonal therapy were enrolled in this study. Pretreatment body weight, height, BMI and WHR were measured. Estrogen, progesteron and c- erb-B2 receptor status were also evaluated in analyses. Univariate and multivariate Cox regression analyses, and Kaplan Meier survival curves subjected to log rank testing were utilized for the survival analyses. Forward likelihood ratio was used for the multivariate selection process. A P value < 0.05 was considered to be significant. Results: Median age was 51 years (range 28 - 75). 36 patients were treated with letrozole and 10 patients with anastrozole. Median body weight, height, WHR and BMI were found to be 68.5 kg (range 46 - 115), 156 cm (range 137 - 167), 0.91 (range 0.7 - 1.2), and 28.7 (range 18 - 45), respectively. Factors associated with overall survival in the univariate analysis were age, c-erb-B2 expression intensity (+++ versus others by immunohistochemistry), and WHR, whereas only WHR retained significance in the multivariate analysis. Likewise, predictors of progression free survival were c-erb-B2 expression intensity and WHR. However, none of these factors was significant in the multivariate analysis. Median overall survival figures were 472 days versus unreached for patients with a WHR of <0.92 and =0.92 (Log rank statistic = 9.76, P = 0.002). Similarly, the corresponding progression free survival figures for patients with a WHR of <0.92 and =0.92 were 423 versus 1,004 days (Log rank statistic = 6.37, P = 0.012). Conclusions: This is the first report examining and suggesting the value of abdominal fat distribution in relation with benefit from AIs in metastatic breast cancer. Our results should be validated in larger series. No significant financial relationships to disclose.

The aim of this study was to assess the prognostic and predictive value of an untargeted assessment of tumor fractions in the plasma of metastatic breast cancer patients and to compare circulating tumor DNA (ctDNA) with circulating tumor cells (CTC) and conventional tumor markers. In metastatic breast cancer patients (n = 29), tumor fractions in plasma were assessed using the untargeted mFAST-SeqS method from 127 serial blood samples. Resulting z-scores for the ctDNA were compared to tumor fractions established with the recently published ichorCNA algorithm and associated with the clinical outcome. We observed a close correlation between mFAST-SeqS z-scores and ichorCNA ctDNA quantifications. Patients with mFAST-SeqS z-scores above three (34.5%) showed significantly worse overall survival (p = 0.014) and progression-free survival (p = 0.018) compared to patients with lower values. Elevated z-score values were clearly associated with radiologically proven progression. The baseline CTC count, carcinoembryonic antigen (CEA), and cancer antigen (CA)15-5 had no prognostic impact on the outcome of patients in the analyzed cohort. This proof of principle study demonstrates the prognostic impact of ctDNA levels detected with mFAST-SeqS as a very fast and cost-effective means to assess the ctDNA fraction without prior knowledge of the genetic landscape of the tumor. Furthermore, mFAST-SeqS-based ctDNA levels provided an early means of measuring treatment response.
